Several solvents had been used to extract the SARA (Saturate, Aromatic, Resin and Asphaltene) constituents of bitumen. The quantification of such extracts also abounds in open literature but in this ...

Hybrid bitumen extraction (HBE) at ambient conditions has potential, as an alternative to the currently used modified Clark hot water extraction (CHWE), to reduce thermal energy intensity and ...

Several waterless extraction methods being piloted that use less energy, produce fewer emissions EDMONTON—Oilsands producers have been under siege for years, with environmentalists, politicians and ...

The efficient recovery of bitumen, a highly viscous form of crude oil, poses significant technical and economic challenges. In recent years, researchers have developed advanced experimental techniques ...

Water-based extraction process (WBEP) has been successfully applied to bitumen recovery from Athabasca oil sand ore deposits in Alberta. In this process, two essential steps are involved. The bitumen ...

Using the nuclear magnetic resonance (NMR) method, scientists have learned to noninvasively determine the composition of petroleum bitumen in half an hour in the core itself (sample). The technology ...

Researchers at the University of Calgary are promising dramatic improvements in the costs and environmental performance of the oil sands with technology they hope to perfect at a new research centre.

The fire at the quality assurance laboratory office at BBMP’s headquarters might have been caused because of a chemical reaction going wrong while conducting a bitumen extract test for asphalt, ...
